Radiographic findings in young llamas with forelimb valgus deformities: 28 cases (1980-1988)

Twenty-eight llamas with a mean age of 6.2 months had bilateral forelimb valgus deformities. The range of valgus deformity, as measured on a craniocaudal radiographic view, was 6 to 25 degrees, with a similar degree of deviation in each limb. Morphologic abnormalities in the distal portion of the radius and ulna were more prominent in the ulna and included metaphyseal and epiphyseal flaring, physeal ectasia, and metaphyseal sclerosis. Distal radial epiphyseal ectasia, and metaphyseal sclerosis. Distal radial epiphyseal wedging was believed to be secondary to the ulnar deformity. Radial bowing with lateral and caudal concavity and unequal cortical thickness was evident. Epiphyseal and metaphyseal flaring with physeal ectasia was noticed in the distal portion of the third and fourth metacarpal bones. Carpal bones were unaffected.
